That's sort of the point, isn't it? Among other things, there would be none of those evil, selfish "tax havens".
Under any oligarchy/tyranny there is always a counter culture. It is inevitable. The more intense the tyranny the more the CC is driven underground. The enemies of the OWO are not outside the system. They are embedded, like cancerous cells, bringing chaos to the best laid plans of the masters of the universe.
